Lots of talk on the forum about synthetic supplements so I thought I'd put together a list of the plants/herbs that I know are beneficial in penis enlargement.
Other:
cocoa (best source of L-Arginine)
oysters (best source of Zinc)
cayenne (relaxes and desensitizes the body making you last longer)
the sun! (vitamin D inhibits prostate cancer)
tongkat ali boosts test levels in most males.
Goji berries have it all and anything else high in zinc, magnesium, b-vitamins, potassium and amino acids.
